- AUTOMATIC MINE-OAR STOP-AND RELEASE.

" To all whom it may concern Be it known that 1, WILLIAM R. ANDER- soN,a citizen of the United States, andrresident of Worden, Madison county, Illinois, have invented certain new and useful Improvements in Automatic-Mine-Car Steps and Releases, of which the following is '3. specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof- My invention relates to improvements in automatic mine car stops and releases, and the object of my invention is to construct an improved automatic car stop and release carand wherein the act of stopping and releasing 'a car is brought about solely by the cage and a car entering the cage.

VVith' the above purposes in view my invention consists in certain novel features of construction and arrangement of parts as will be hereinafter more fully described,

pointed out in the claims and illustrated by the accompanying drawings, in which- Figure 1 is an elevation illustrating an apparatus for stopping and releasing mine cars constructed according .to my invention;

Fig. 2 is a fragmental end elevation and Fig. 3 is a plan illustrating my invention.

Referring by numerals to the accompanyingdrawingsr 5 designates the cage having the rails 6 thereon.

7'desi'gnates a track-way located 'in' an entry ,(not shown) communicating.withthe. shaft (not shown), in which the cage f operates.

The form of cage shownis a dumping,

cage,"and init's specific construction and relatlve arrangement withthe track-Way 7 1s common and forms no part of my invention.

8 designates an ordinary mine car having the ordlnary flanged wheels 9 for rid ng over the rails 6 and 7 which'wheels are mounted upon the ordinary axles. 10.

11-11 designates plates which are secured to the platform'of the cage 5 parallel and preferably between the rails 6.

12 designates car arms having hooks stops in the form of at their ends. These stops 12 are arranged in oppositely disposed pairs and each pair-is pivotally secured to the bearing-plates 11.

13 designates guides for the outer free ends of the plates 21 and 4.0, and 11 desig- Specification of Letters Patent.

Application filed September 15,1913. Serial No. 789.867.

nates extensile coil springs for normally holding the plates elevated, so that the stops 12 will be normally in positions to engage the axles of'the cars.

15 designates a hanger depending from the platform of the cage and arranged for the'support of a pivoted arm 16. Carried at 16 isa dog 17 which is pivotally carried by the arm. This dog is located adjacent the receiving end of the cage. At the other end of the arm 16 there is a spring 18 and extending upwardly from the free end of said spring is a rod 19 which is adjustable as to length by means of a turn-buckle 20. This rod is connected with the plate 21 so that when the arm 16 is operated upon a. movement of the cage, as will be more" fully explained hereinafter, the plate will be drawn downwardly and the forward pair of stops 12 will be released from'the forward axles of the car.

. may have a limited'movement with the car.

2 1' designates a draw-bar secured to the rod 22' at itsone end and to a retractile coil spring 25 at its other end which means serves as a cushion for the stopping of the cars on the cage.

26' "designates "a piston rod having a pivotal connection 27 with the plate 21 which to the oppositeiend of the pistenrod 26 is a piston 28 arranged for movementin a dashpot29 provided with a slow-leak valve 30 and an'intake valve 31. This means operates as a cushioning device auxiliary to previously described comprising the spring 25.

Secured in the path'ofv travel of the dog 17. isa plate 32 which is pivotally supported in a bearing 33. This plate 32 is mounted in such manner as to have a limited downward movement at'its free end so as to act as a catch for said dog when the cage descends, and the plate is hinged so that when the dog moves beneath said plate the plate may be'moved automatically out of the path of the dog, so that the dog may ascend with the cage.

Mdesignates a shaft which is rotatably cage platform. Arranged on said shaft in alinement with the dog 17 is a bell-crank 35, having a counter- Secured balance 36. Connecting the arm of the bellcrank 35 provided with the counterbalance 36 and the dog 17 is a rod 37, and connected terbalance 36 the levers 38 are each held in .1 the r operative positions and the rod 37 V 46 arranged to holds the dog 1 the plate 32.

rear'stops, and secured to-said plate is a rod 41 which extends downwardly through an opening formed in the platform'of the cage. Beneath the cage platform the. rod 41 connects with the lever 42 which is pivot ally secured to a bearing 43 depending from the cage platform. At the free end of the lever 42 there is secured a pedal 44 whichextends upwardly through the cage plat form. The stem of the said pedal is.pro-

vvided with ratchet teeth 45 and secured to the platform adjacent said. stem is a plate said pedal, whereby when the pedal-is depressed said teeth andsaid plate will serve. By this.

At this time a car on the rails 7 is moved to enga e the car on the cage and force it off of the cage. In the movement of said second car, which is a filled car, the
